Abstract
La presente invención se refiere a un sistema de comunicaciones para transmitir señales de comunicación y que incluye medios para suprimir la interferencia electromagnética, el sistema comprende: medios para generar una señal de comunicaciones, medios para recibir la señal generada, medios no protegidos para llevar la señal generada en una modalidad equilibrada, de los medios de generación de la señal a los medios para recibir la señal generada, y medios divisores de voltaje, que incluyen un conductor metálico que se extiende longitudinalmente y medios substancialmente transparentes a la modalidad funcional equilibrada y que tienen una impedancia relativamente alta hacia la modalidad funcional longitudinal para disminuir substancialmente el voltaje longitudinal entre los medios no protegidos para llevar la señal generada.The present invention relates to a communication system for transmitting communication signals and which includes means for suppressing electromagnetic interference, the system comprises: means for generating a communication signal, means for receiving the generated signal, unprotected means for carrying the signal generated in a balanced mode, from the signal generating means to the means for receiving the generated signal, and voltage divider means, including a longitudinally extending metal conductor and means substantially transparent to the balanced functional mode and which they have a relatively high impedance towards the longitudinal functional modality to substantially decrease the longitudinal voltage between the unprotected means to carry the generated signal.
